Mabungwe Oyang'anira MCU
MCU monga gawo lalikulu la IOT, idapangidwa mwachangu mzaka zaposachedwa.
Bokosi lolamulira la MCU, lokhala ndi dzina lonse la Micro Controller Unit, limatha kuphatikiza kachipangizo koyang'anira zinthu zing'onozing'ono, zida zina zamagetsi ndi PCB yophatikizidwa yoyang'anira mabwalo akunja. Kutengera mawonekedwe a muyeso wamafuta ndi zinthu zowongolera, chilengedwe, ndi mawonekedwe, bolodi loyang'anira la MCU likuyenda kuntchito yopanga ndalama, kukonza kudalilika kwa mafakitale, ndikupanga mawonekedwe a mawonekedwe apakompyuta mosavuta komanso mosavuta .
Kugwiritsa ntchito ma board a MCU:
Nthawi zambiri imagwiritsidwa ntchito pamaulamuliro ena osavuta a mafakitale, monga kuyeza & kuwongolera makina, mita yamagetsi, zinthu zamagetsi, mawonekedwe anzeru, ndi zina zambiri. zida, masikelo amagetsi, zolembera ndalama, zida zamaofesi, zida kukhitchini, ndi zina. Kuyambitsidwa kwa MCU sikuti kumangogwira ntchito za zinthuzo, kumawongolera magwiridwe antchito, komanso kumakwaniritsa Gwiritsani ntchito.
Mfundo zoyang'anira ma MCU:
Ndizosavuta kugwiritsa ntchito chilankhulo cha C kapena zilankhulo zina zowongolera kuti mulembe njira zowongolera kuti mukwaniritse cholinga choyang'anira mafakitale.

Kusiyana pakati pa MCU ndi PLD:
(1) MCU imayang'anira zida zogwiritsira ntchito kuti zizigwira ntchito posintha doko la I / O kudzera pulogalamu; PLD isintha mawonekedwe amkati mwa chip kudzera pulogalamu.
(2) MCU ndi chip, koma sichingagwiritsidwe ntchito mwachindunji; PLC ili ndi mawonekedwe opangidwa okonzeka, ndiosavuta komanso odalirika kuti muwagwiritse ntchito bwino pamafakitale, kenako ndikulumikiza kulumikizana ndi makina amunthu kuti awongolere mwachindunji.
(3) Chip chip cha MCU ndi chotchipa, ndipo chimagwiritsidwa ntchito kuwongolera zokhazokha zamagetsi mumakampani opanga; PLC ndioyenera kuyendetsa mafakitale basi.
